TO ALL WliOM IT MAY CONCERN:

Be it known that I, GEORGE MOONEY, of Providence, Providence county,Rhode Island, have invented a new and improvedArgand Gas-Burner; and Ido hereby declare that the following is a full, clear, and exactdescription thereof, which will enable others'skilled in the art to makeand use the same, reference being had to the accompanying drawings,forming part of this specification.

' This improvement relates to the manner in which the burner is formcd,and to the method employed for obviating the noise common to the argandburner-as at present constructed.

And the. invention consists, firstly, in foriirihg the upper chamber otthe burner of one piece of sheet metal; secondly, in forming thejet-apertures without drilling; and, thirdly, in the employment of ascrew inserted in the burner, adjustcd to prevent the noise incident toburners of this class, as hereinafter more particnlarly described.

The figures in the drawing are designed to illustrate the method offorming the burner, and also the manner in which the regulating-screw isapplied.

Figure 1 represents the burner formed and partially completed, it beingavertical section through the line a: 2;, fig. 2.

Figure 2 is a. top view of the outer ring or casing of the burner,showing grooves in its inner side Figure 3 is a vertical sect'icnof fig.4 through the line yy, showing the manner in which the burner isconstructed.

Figure 4 is a top view of the burner complete, showing thejet-apertures.

Similar lettersof reference indicate corresponding parts.

The burner is formed of one piece of sheet metal, as represented in fig.1, which is swn-ged or pressed into the form seen, showing a doublering. 7 The outer ring a is grooved or chambered out on its inside, thei grooves extending from the top or rim to one half, more or less, ofits depth. Those grooves or channels form, a in connection with theinner ring, the gas-jet apertures. To complete the burner, the upperportion or cap of the inner ring is removed, and the top of the groovedring a is pressed inward until it comes in contact with the inner ring0. The two rings thus being brought together complete the jet-apcrtures,and leave a chamber,- e, beneath for. the circulation of the gas. B isthe burner-stand or shank, which is attached to the gas-fixture by thescrew in its bottom end, as seen. cl is the upper part, forming across-bar, to which the burner is attached. There are apertures throughthe stand and'the bar, forming a T, which communicate with the chain.her in the burner. f is a screw, which passes into the upper end of thestand, and is enclosed by the sides of the burner. By turning this screwup or down, an adjustable gas-check is formed, which prevents the gasfrom producing the noise so offensive in the ordinary argand burner. Asthe screw is inserted further into the stand the smoothness ot the undersurface of the latter is destroyed, and the gas allowed to impingedirectly against the end.of the screw, whose sharp edges destroy thesmooth flow of gas, producing the cil'e ct above mentioned.

I do not claim the screw in itself considered, nor do I claim regulatingthe flow of gas in an ordinary gas-burner; but having thus described myinvention,

I claim as new, and desire to secfire by Letters Patent-- 1. Forming anargand gas-burner of one piece of metal, substantially as described.

2. Forming the gas-jet apertures through the top or rim of the burnerwithout drilling, and substantially as-dcscribed.

3. The screwf, forming an adjustable check, in combination with anargaud burner, for the purpose of producing a still light, as hereinshown and described.
